BBK R&D department developed these headers (P/N: 16330) with one thing in mind--getting even more horsepower and torque out of the all-new 5.0L Mustang that is already putting out nearly twice the horsepower of its predecessor!
This all new rugged BBK header design is constructed with 1-3/4" CNC Mandrel-Bent tubing and solid 3/8" laser cut exhaust flanges. Initial testing is showing gains of around 30+ horsepower with the high flow catted X-pipe. This direct-fit header features a ceramic coated finish. All headers include a set of new gaskets, required hardware and detailed installation instructions for installation.
*Ford changed the thread pitch on the header bolts midway through productions. 5.0L Mustangs made from March 2010-August 2010 require fine thread header bolts, 5.0L Mustangs made after August 2010 require coarse thread bolts. BBK includes bolts for either application. It is VERY important to make sure that you use the correct bolts--serious damage can be caused by using the wrong bolts.
Tech Tip: All 2015-2020 GT Mustangs will require P/N: EX1816 or custom connection pipes made for installation. In addition, 2015-2017 GT Mustangs must use BBK Front Extension Harnesses (sold separately) P/N: O2H6. And 2018-2020 GT Mustangs must use BBK Front O2 Extension Harnesses (sold separately) P/N: BBK1121.
Please Note: These headers are NOT compatible with RHD (Right-Hand-Drive) Models.
